a Transmission FTIR, b Raman, and c EDS spectra of sample S9 from house post 16/568, i.e. a scraping of green paint from the eye of a human figure. The presence of Prussian blue was inferred from the identification of FTIR and Raman bands lying at 2094 cm− 1 as well as 278, 538, 2093, and 2155 cm− 1, respectively, and from the concurrent detection of iron (Fe) and nitrogen (N) in EDS data. Other compounds identified in the FTIR and Raman spectra include gypsum, calcite, barite, quartz, and an organic medium
